Abstract
Objective: Bilateral coordination skills are one of the key factors in performing simple to skillful sports task, so far the differences between ball and non-ball fields have not been determined. Therefore, this study aimed to investigate the differences in asymmetric bilateral coordination between male and female athletes in ballplayers and non-ballplayers. Methods: The samples of this study were randomly selected from the young girls and boys (Mean±SD of age 26.00±4.50) in ball fields (14) and non-ball fields (16) of the Faculty of Physical Education of the University of Tehran. All subjects had complete visual acuity and the consent form of the research. The instrument of Vienna was used to measure peripheral visual. Results: The statistical results of MANOVA test showed that there is significant difference in asymmetrical bilateral coordination between ballplayers and non-ballplayers and girls and boys (P≥0.05). Conclusion: The results of this study showed that asymmetric bilateral coordination performing in ball players had better than non-ball players and girls than boys. According the importance of bimanual coordination skills in the implementation of championship sports, as well as considering gender differences and the positive impact of ball exercises on ball coordination, sports coaches can provide training, especially at a younger age, to facilitate learning of this fundamental skill.
Highlights
One of the results of this study was that girls had a significant advantage over boys in performing asymmetric bimanual coordination tasks
The results of some studies by MRI showed that the area of the corpus callosum in girls was larger than boys, as a result of which the exchange of information between the two hemispheres of the brain was more accessible, which makes girls superior to boys in performing bimanual coordination tasks [30]
The better performance of ball sports athletes compared to non-ball sports athletes in performing asymmetric bimanual coordination skills was another result of this study, which can be related to years of practice and experience working with both hands and balls in the ball sports group
Summary
These results confirm that ball sports athletes spent less total time on the task. In examining the female athletes’ error time (with a mean of 0.34 seconds) and male athletes (with a mean of 0.61 seconds), it can be concluded that girls had fewer errors and had a higher degree of accuracy in performing bimanual coordination task. MANOVA statistical results indicated that there was a significant difference between girls and boys in the dependent variables of “performance time” (speed) and “error time” (accuracy) (P≤0.05). The results of this study confirmed that in performing asymmetric bimanual coordination tasks, ball sports’ athletes performed better than nonball sports’ athletes, and girls performed better than boys
